I just don't know

What will my life be if we don't have children? What am I suppose to do? How horrible can that feel? 38, been ttc #1 with no success. How can I know if God will bless me? Why must I go through all this suffering? I've already been through so much. So hard not to be concerned with age and everything else on my mind. It feels like it needs to happen now if it's going to happen. I didn't see this struggle coming. I thought I'd have zero problem getting pregnant. Unexplained infertility with low amh.
